3. Saving hours of homework time: The REAL timesaver comes in using this little mini-computer to do all your homework! You know how you always get 15 homework problems, all the same.... Tell the calculator how to do one, and it will do all the rest for you! Let's use the data from list 1 again to save all that typing. Look the lists over, you should have 0,1,2,3,4,5,6 in list 1, right? Now let's make a graph of x2. That would mean putting 0,1,4,9,etc in list 2. So lets tell the calculator to do that: Printed in yellow on the calculator over the number 1 is L1, so hit (L1), the (x2) button, then the (sto) button, then (L2), then (enter). Now when you look in the lists there the numbers are. That last command line took all the numbers in list 1, squared them, and stuck the answer in list 2. I want to point out two things: a. it will do much more complicated things, like (3xL1+4)5 just as fast! b. it will do a list of 100 numbers just as fast! Graph the last problem to see a y vs x2 graph. You know, if you wanted a x2 vs y graph, you could just change the plot 1 command so that x-axis is L2, y-axis is L1, and now you have the other graph - try doing that on a piece of graph paper!
